【摘要】 林下茶园复合经营模式作为现代生态农业的重要发展方向，对推动茶产业可持续发展具有重要意义。该研究以广西壮族自治区茶区为研究对象，采用长期田间试验与产业调研相结合的方法，系统探究了林木配置、光环境调控及病虫害绿色防控等关键技术，并运用工程经济学模型对投入产出结构进行全维度量化分析。结果表明，茶园遮阴度控制在30%～50%时，茶叶品质可达最佳状态；建立生态防控体系后，化学农药使用量可减少45%以上；林下茶园复合经营模式每667 m~2综合收益为2.8万元，较传统茶园提高67.6%，投资回收期为3.5 a，每667 m~2净现值为4.65万元，内部收益率为28.7%。该模式有效实现了生态保护与经济增长的良性耦合。更多还原

【Abstract】 The integrated management model of tea gardens under forest cover, as an important direction of modern ecological agriculture, is of great significance to the sustainable development of the tea industry. In this study, the tea area in Guangxi Zhuang Autonomous Region was taken as the research object, and the key technologies such as forest allocation, light environment regulation and pest green prevention and control were systematically optimized by combining long-term field experiments with industrial research. The engineering economics model was used to quantitatively analyze the input and output in all dimensions. The results showed that the quality of tea was the best when the shading degree of tea garden was controlled at 30 % ～ 50 %. After the establishment of ecological prevention and control system, the use of chemical pesticides can be reduced by 45.2 %. The comprehensive income per 667 m~2 of the model was 28 000 yuan, which was 67.6 % higher than that of the traditional tea garden. The investment recovery period was 3.5 years, the net present value per 667 m~2 was 46 500 yuan, and the internal rate of return was 28.7 %. The model effectively realized the benign coupling of ecological protection and economic growth.更多还原
